One spring cavity 34, spring chamber inner sidewall are equipped with screw thread, and the bottom of chamber of spring cavity is the screw thread connecting with the sidewall thread of spring cavity
Bottom cover 37.A blind hole is formed after screw thread bottom cover and spring cavity cooperation, spring 35 is cylindrical spring, is set in the blind hole.Screw thread
Design has an annular groove on bottom cover, the end adapter of shape and size and spring, the grafting of spring outwards end in a ring groove,
Form position-limiting action.The inner end of spring adjusts core fixing seat 38 with hydraulic pressure and abuts.Hydraulic pressure adjusts core fixing seat and is also connected with simultaneously
One pressure stabilizing valve block 43, the periphery of pressure stabilizing valve block are fixed, and middle part can deform in right amount along the elastic force direction of spring, to make to act on
The elastic force that hydraulic pressure adjusts the spring in core fixing seat is more linear.Hydraulic pressure adjusts core fixing seat and is equipped with screw thread, is threaded with
Hydraulic pressure adjusts core 39.Hydraulic pressure adjusts the column being set in intermediate channel that core is a perforation, fixing end including left end, in
Between central sections and right end free end.Fixing end adjusts core fixing seat with hydraulic pressure and is threadedly coupled.Between fixing end and central sections
Equipped with intermediate channel cover plate 36, under normal conditions, intermediate channel cover plate is connected to the downstream end of intermediate channel under the effect of elasticity
On face.Voltage stabilizing module is also devised with hydraulic pressure and adjusts core guiding blind hole 40, and it is blind hole, axial direction and spring that hydraulic pressure, which adjusts core guiding blind hole,
Elastic force direction it is parallel, hydraulic pressure adjust core free end adaptation be plugged on hydraulic pressure adjust core guiding blind hole in, and hydraulic pressure adjust
O-ring 41 is socketed on the lateral wall of the free end of core.Hydraulic pressure, which adjusts protrusion circular on the lateral wall of the central sections of core, one
Limit rib 42 is enclosed, the diameter of limit rib is greater than the diameter of intermediate channel.
The voltage-stabilizing combined solenoid valve of this example, the working method positioned at the guide electromagnetic valve of upstream are identical as traditional structure:
Under normality, 11 no power of line packet, iron core seal head 14 is located below, and is close to pilot hole upper surface and is realized sealing, at this time valve block 16
Top and the full water body with pressure of water inlet.If you need to be connected, so that the energization of line packet is generated magnetic force and pick up iron core 13, iron core upwards
Seal head leaves pilot hole upper surface, and depressurization state, the part in the water with pressure being located above is by pilot hole downlink
It flows into annular and separation side wall, the pressure in valve block lower outer cylinder is made to be greater than the pressure above valve block, make at this time in pressure
Under, the water body in valve block lower outer cylinder pushes up upwards, and valve block is made to overcome valve block reset spring uplink, the valve block sealing of lower section
Pad 17 loses the pressure of top valve block, is deformed, and leads between valve block lower outer cylinder and inner cylinder i.e. water inlet
Conducting is formed between side and annular and separation interior, water body can be flowed away along this conduction path to water outlet.If you need to by,
Just power off line packet, the decline of magnetic force disappearance iron core, iron core self gravity and the dual strength of valve block reset spring 15 act on valve block
On, so that valve block is pushed valve block gasket downlink, covers annular spaced side walls upper end opening again.Iron core seal head downlink closure is first
Guide hole upper surface.Water body is constantly poured in from water inlet, and by being preset in valve seat deflector hole flows into above valve block, leads
It causes the pressure above valve block persistently to increase, valve block gasket is firmly enclosed in by annular and separation sidewall upper opening by pressure difference
On, form cut-off effect.
In the moment of the valve block opening and closing of the guide electromagnetic valve of upstream, very big differential water pressures can be generated to downstream direction.?
When upstream hydraulic pressure increases suddenly, intake tunnel in Voltage stabilizing module is synchronous with intermediate channel hydraulic pressure to be increased, and is pushed intermediate logical
Road cover plate overcomes the resistance of spring to move to the left, opens intermediate channel, intermediate channel is connected to exhalant canal, makes water flow can
With flow further downstream.In the process, hydraulic pressure is bigger, bigger to the pressure of intermediate channel cover piece, and the compressive deformation of spring is just
Stronger, the power that reaction pushes to the right on intermediate channel cover plate is also bigger, and eventually the thrust in the left and right sides is equal
In the case of, intermediate channel cover plate tends to be static, and the gap size between intermediate channel and exhalant canal no longer changes, flow rate of water flow
Flow region is stablized.At the same time, the hydraulic pressure of intermediate channel is bigger, water flow is more anxious, by taper cross sectional shape generate to water
The effect that pressure adjusts core is also stronger, promotes hydraulic pressure to adjust core and moves to the right, similarly synchronizes intermediate channel cover plate and move right
It is dynamic, reduce the gap between intermediate channel and exhalant canal.And hydraulic pressure adjusts core when being moved to the left, it is blind that hydraulic pressure adjusts core guiding
Negative pressure of vacuum is kept in hole, is also further improved hydraulic pressure and is adjusted core and moves right the power of reset.These power are combined work
It on intermediate channel cover plate, is acted on intermediate channel cover plate to the left by the thrust that hydraulic pressure generates, the two realizes balance, downstream
The hydraulic pressure of water be maintained for stablizing, to realize abatement upstream end hydraulic pressure to keep the effect of downstream stable water pressure.And work as
When upstream hydraulic pressure reduces suddenly, hydraulic pressure adjusts core and moves right, and hydraulic pressure adjusts core to hydraulic pressure in the elastic force of spring, intermediate channel
The negative pressure that active force, hydraulic pressure adjust core guiding blind hole also slowly reduces therewith, until the pressure phase of intermediate channel cover plate two sides
Deng forming the downstream end face that intermediate channel is completely covered in new balance or intermediate channel cover plate, water flow cut completely
It is disconnected.
Screw thread bottom cover is rotatable, the elastic force of adjustable springs, to obtain suitable hydraulic balance point.Hydraulic pressure adjusts core
Relative water pressure, which adjusts core fixing seat, to adjust the position of the conic section of central sections on core with screw thread rotation, adjustable hydraulic pressure
It sets, to form different active forces under same hydraulic pressure.
Using the voltage-stabilizing combined solenoid valve of this example, the energy of medium itself can be relied on, outlet pressure is made to automatically keep stabilization,
Help to maintain the safety of downstream pipeline, valve and watering equipment.
